If the current condition of the attraction is going to be the status quo for months-on-end going forward (and to be clear, it should not be), I really think Universal should consider putting up some version of a "Technical Rehearsal" sign (pick another word instead of rehearsal), saying something like, "Not all effects may be working, etc."
It is just not appropriate (to say nothing of good show) to believe that guests are getting a proper, full experience from the attraction as-is.
